PowerShell Tool Kit - Converting XenServer VHD to VMDK

ohnemus — Wed, 04 Jun 2025 19:38:44 GMT

Hello all!

Does the powershell toolkit provide any ability to convert thin provisioned XenServer VHD's to VMDK's?

If so what is the commandlet used to do that? - (ConvertTo-NcVmdk?)

Thanks for any info you can provide.

Hi,

ConvertTo-NcVmdk is the cmdlet to convert VHD to VMDK.

Please make sure about the XenServer Tools installed on the guest OS, you might want to uninstall it before converting the disk to VMDK.

Thanks,

Thanks for the reply.

We have tried to use the "ConvertTo-NaVmdk" commandlet and get the following error.

PS C:\windows\system32> ConvertTo-NcVmdk -SourceVhd x:\d37fb41f-556d-47c0-ab60-656444be2e5b.vhd

ConvertTo-NcVmdk : Specified argument was out of the range of valid values.

Parameter name: File is not a fixed-size VHD.

Does the VHD need to be a fixed size VHD to work? We can't do this with a thin VHD?

Thanks!

Hello,

The Conversion is supported only for fixed size VHD and monolithic flat VMDK files.

Please convert the dynamic VHD to fixed size VHD before converting it to VMDK.
